Saddle-ride type fuel cell three-wheeled vehicle

Abstract

A saddle-ride three-wheeled vehicle has a fuel cell which generates an electric power by a chemical reaction between a fuel gas and a reaction gas. The three-wheeled vehicle includes a drain pipe which guides water discharged from the fuel cell out of a vehicle body; a rear body to which a pair of left and right rear wheels are journaled; and a linking mechanism which swingably links the rear body and a front body to allow the front body to sway left and right with respect to the rear body, wherein the drain pipe has a drain port between the pair of left and right rear wheels.

       11. A saddle-ride three-wheeled vehicle having a fuel cell which generates an electric power by a chemical reaction between a fuel gas and a reaction gas, the three-wheeled vehicle comprising:
 a drain pipe which guides water discharged from the fuel cell out of a vehicle body; 
 a rear body to which a pair of left and right rear wheels are journaled; and 
 a linking mechanism which swingably links the rear body and a front body to allow the front body to sway left and right with respect to the rear body, 
 wherein the drain pipe has a drain port between the pair of left and right rear wheels, and 
 wherein the fuel cell is attached to the front body and located under a seat for a rider to sit on, wherein the drain pipe includes a first drain pipe portion which guides the water from the fuel cell to under the linking mechanism and a second drain pipe portion which guides the water from under the linking mechanism out of the vehicle body, and wherein the first drain pipe portion and the second drain pipe portion are supported by the vehicle body in a manner that the first drain pipe portion is circumferentially turnable with respect to the second drain pipe portion. 
 
     
     
       12. The saddle-ride three-wheeled vehicle according to  claim 11 , further comprising a reservoir which temporarily stores the water between the first drain pipe portion and the second drain pipe portion, wherein the reservoir is attached to the rear body and the first drain pipe portion is circumferentially turnably engaged with the reservoir. 
     
     
       13. A three-wheeled vehicle comprising:
